*Arslan Senki: same author that wrote Legend of the Galactic Hereoes, and Arakawa from FMA is drawing it.
*Baby Steps: best tennis' manga I've ever read.
*Doubutsu no Kuni: great manga, awesome setting, stuff never seen in manga before. Author is best known for Gash Bell.
*Chihayafuru: Do I even need to explain? It's got two seasons of anime, and it's awesome.
*Ace of Diamond: It's got an anime, good chances of being popular.
*Eden - It's an Endless World!: This is a long shot, but it's a very mature manga that would cater to CR's more mature audience.
*Aku no Hana: It has an anime.
*Giant Killing: A more mature football manga.
*Great Teacher Onizuka: Another long shot, but one of my favorite manga of all time. It's a masterpiece.
*Hajime no Ippo : IT'S FREAKING IPPO! Shame it's got so much chapters to be easily available, but it would be amazing to see it here.
*Historie: amazing historical manga.
*I Am Here!: Great zombie manga, amazingly drawn.
*Kiss×sis: not really a fan, but some ecchi on CR would be good for variety.
*Moyashimon: it has an anime.
*Nodame Cantabile: An amazing josei, good for mature audiences, would be awesome to see it here.
*Ookiku Furikabutte: It has two seasons of anime, and it's freaking great.
*Tonari no Kaibutsu-kun: not that much fan of it, but shoujo for variety, and it's sorta popular.
*Vagabond: Holy shit! One of the best seinens of all time! This is one of those I wish was here the most.
*Vinland Saga: Another extremely high quality seinen, seriously one of the best out there.
*Yankee-kun to Megane-chan: same author as an already licensed manga - Yamada-kun - and just as good.
*Planetes: Amazing story. It has an anime also.

Keep in mind I might not have added all the manga I want because I went through ANN's list pretty fast.

Since none of the print manga publishers have any interest in licensing sports series, I hope CR will pick up Big Windup, Baby Steps and Giant Killing. I suppose Chihayafuru would fall into this category as well.

And Kodansha USA has said on their Tumblr that Bloody Monday hasn't done well enough to justify them picking up the second and third series, so that'd be another one I'd like to see CR go after.

Genshiken: Second Season(http://myanimelist.net/manga/348/Genshiken)
Dates: May 23, 2011 to ? (ongoing)
Volumes: 5 +
Serialized: Afternoon
Notes: From ANN-The Japanese edition has two parallel volume numbering systems: the title now includes 二代目の壱 (Nidaime no Ichi, literally "First of the Second Generation") in kanji, marking the new story arc, but the volumes start from 10, indicating the continuation from Genshiken volume 9.

Figured this was the best place to post this....the following manga will be on CR manga in the future (via their home page for the IOS app)
Animal land
Sankarea
Air gear
Negima
Vinland saga
Battle angel altia
Genshiken nidaime
Guessing sankarea,animal land,Vinland saga,altia and genshiken will be simulpubs.
